A series of intensifying wildfires across the western United States has resulted in the deaths of three federal firefighters and the implementation of state-level emergency measures in Utah and Colorado.

美國西部一系列不斷加劇的山火，導致三名聯邦消防員死亡，且猶他州與科羅拉多州已實施州級緊急措施。

The fatalities occurred on June 27 during a 'burnover' incident involving personnel from the U.S. Wildland Fire Service and the U.S. Forest Service. This event transpired while crews were engaged in an interagency response to the Knowles and Gore fires along the Colorado-Utah border. Two additional personnel sustained burn injuries and are currently receiving medical treatment. The Knowles and Gore blazes have since coalesced with other fires to form the Snyder Mesa Fire, which has consumed approximately 28,000 acres and remains uncontained.

此次傷亡發生於 6 月 27 日，當時美國野外消防局與美國林務局的人員遭遇了「火燒過頂」事故。該事件發生在救援隊於科羅拉多州與猶他州邊界進行跨部門應對 Knowles 及 Gore 山火期間。另有兩名人員遭受燒傷，目前正接受醫療治療。Knowles 與 Gore 的火勢隨後與其他火場合併，形成了 Snyder Mesa 山火，目前已燒毀約 28,000 英畝土地且尚未受控。

Concurrent with these events, the Cottonwood Fire in Beaver County, Utah, has emerged as the largest active wildfire in the United States, covering over 144 square miles. The rugged topography of the region has impeded the deployment of heavy machinery and engines, thereby decelerating containment efforts. The blaze has caused significant structural damage to summer cabins and the Eagle Point ski resort. In Arizona, the Pocket Fire near Sedona has expanded to over 5,500 acres, while other blazes near the Grand Canyon and Kendrick Mountain have necessitated evacuation orders.

與此同時，猶他州比弗縣的 Cottonwood 山火已成為美國最大的活躍山火，覆蓋面積超過 144 平方英里。該地區崎嶇的地形阻礙了重型機械與消防車的部署，從而減緩了圍堵進度。這場大火對夏季小屋及 Eagle Point 滑雪場造成了嚴重的結構損壞。在亞利桑那州，塞多納附近的 Pocket 山火已擴大至 5,500 英畝以上，而大峽谷與 Kendrick Mountain 附近的其它火場則已觸發疏散令。

Environmental antecedents contributing to this volatility include record-low snowpack and the warmest winter on record in Utah, alongside widespread regional drought. The National Weather Service has issued 'red flag' warnings across California, Arizona, and New Mexico, citing a combination of high temperatures, low humidity, and wind gusts reaching 50 mph. These conditions prompted the National Weather Service in Salt Lake City to utilize the 'particularly dangerous situation' designation for the first time in its history.

導致此次不穩定狀態的環境前兆包括猶他州紀錄最低的積雪量與有史以來最溫暖的冬季，以及區域性的廣泛乾旱。國家氣象局已向加州、亞利桑那州與新墨西哥州發布「紅旗」警告，指出高溫、低濕度與時速達 50 英里的陣風共同影響。這些條件促使鹽湖城的國家氣象局在其歷史上首次使用「極端危險情況」這一指定稱號。

Institutional responses have been extensive. Governor Spencer Cox of Utah declared a state of emergency and implemented a fireworks prohibition. Similarly, Colorado Governor Jared Polis declared a disaster emergency and authorized the deployment of the National Guard. To mitigate further risk, utility providers including Rocky Mountain Power initiated precautionary electrical shut-offs in high-risk zones. Nationally, nearly 3 million acres have burned since the commencement of the year, a figure exceeding the ten-year rolling average.

機構應對措施十分廣泛。猶他州州長 Spencer Cox 宣布進入緊急狀態並實施禁止燃放煙火令。同樣地，科羅拉多州州長 Jared Polis 宣布災害緊急狀態並授權部署國民警衛隊。為了降低進一步風險，包括 Rocky Mountain Power 在內的電力供應商在高風險區域啟動了預防性停電。自年初以來，全美已有近 300 萬英畝土地被燒毀，該數值超過了十年滾動平均值。

The western United States remains under critical fire weather warnings, with multiple large-scale blazes remaining uncontained and regional resources heavily taxed.

美國西部仍處於嚴重火災天氣警告中，多場大規模山火尚未受控，區域資源承受巨大壓力。
